Generalized Hydrodynamics of Bloch Oscillations in the Absence of a Lattice
Stefano Scopa, Philip Zechmann, Michael Knap +2
Objects subjected to a constant force generally increase their velocity over time. This expectation fails whenever their energy is a smooth and periodic function of momentum, resul…
Anomalous hydrodynamic fluctuations in the quantum XXZ spin chain
Takato Yoshimura, Žiga Krajnik, Alvise Bastianello +1
The quantum XXZ spin-1/2 chain features non-Gaussian spin current fluctuations in the regime of easy-axis anisotropy. Using ballistic macroscopic fluctuation theory, we derive the…
Realization of fractional Fermi seas
Yi Zeng, Alvise Bastianello, Sudipta Dhar +7
The Pauli exclusion principle is a cornerstone of quantum physics: it governs the structure of matter. Extensions of this principle, such as Haldane's generalized exclusion statist…
Exotic critical states as fractional Fermi seas in the one-dimensional Bose gas
Alvise Bastianello, Yi Zeng, Sudipta Dhar +7
Critical quantum field theories occupy a central position in modern theoretical physics for their inherent universality stemming from long-range correlations. As an example, the To…
Experimental observation of ballistic correlations in integrable turbulence
Elias Charnay, Adrien Escoubet, Francois Copie +4
Unequal-time correlation functions fundamentally characterize emergent statistical properties in complex systems, yet their direct measurement in experiments is challenging. We rep…

Milena Horvath, Alvise Bastianello, Sudipta Dhar +5
Bethe strings are bound states of constituent particles in a variety of interacting many-body one-dimensional (1D) integrable quantum models relevant to magnetism, nanophysics, col…
Universal efficiency boost in prethermal quantum heat engines at negative temperature

Heat engines near the adiabatic limit typically assume a working medium at thermal equilibrium. However, quantum many-body systems often showcase conservation laws that hinder ther…
Observation of a generalized Gibbs ensemble in photonics
Alvise Bastianello, Alexey Tikan, Francois Copie +2
In generic classical and quantum many-body systems, where typically energy and particle number are the only conserved quantities, stationary states are described by thermal equilib…
Scattering Theory of Chiral Edge Modes in Topological Magnon Insulators
Stefan Birnkammer, Michael Knap, Johannes Knolle +2
Topological magnon insulators exhibit robust edge modes with chiral properties similar to quantum Hall edge states. However, due to their strong localization at the edges, interact…
Landau-Lifschitz magnets: exact thermodynamics and transport
Alvise Bastianello, Žiga Krajnik, Enej Ilievski
The classical Landau--Lifshitz equation -- the simplest model of a ferromagnet -- provides an archetypal example for studying transport phenomena. In one-spatial dimension, integra…
